I am using M65 Module . Oftenly I am getting CME error during HTTP post .
while I have uploaded my data using Postman API 100K time , not a single time I faced any issue .
please look at my code .
bool mygsm_httppost(char* buffer)
{
gsm_printf(“[GSM] HttpPost() Begin\r\n”);
char str[255]={0};
int bufferlen= strlen(buffer);
if (gsm_lock(10000) == false)
{
gsm_printf(“[GSM] HttpPost() failed!\r\n”);
return false;
}
// memset(&Ans_ATC,0,sizeof(Ans_ATC));
do{
sprintf(str,"AT+QHTTPURL=%d,30\r\n",bufferlen-2);
if(gsm_command(str, 1000 , NULL, 0, 2, "\r\nCONNECT\r\n", "\r\nERROR\r\n")!=1)
break;
sprintf(str,"%s",buffer);
gsm_printf("\r\n%s\r\n",str);
if(gsm_command(str, 30000 , NULL, 0, 2, "\r\nOK\r\n", "\r\nERROR\r\n")!=1)
break;
if(gsm_command("AT+QHTTPPOST=1,50,10\r\n", 120000 , NULL, 0, 2, "\r\nCONNECT\r\n", "\r\nERROR\r\n")!=1)
break;
if(gsm_command("1\r\n", 50000 , NULL, 0, 2, "\r\nOK\r\n", "\r\nERROR\r\n")!=1)
break;
gsm_delay(1);
if(gsm_command("AT+QHTTPREAD=30\r\n", 50000 , str, sizeof(str), 2, "\r\nCONNECT\r\n", "\r\nERROR\r\n")==1)
{
gsm.gprs.Transmit_Success=1;
break;
}
} while(0);
if(gsm.gprs.Transmit_Success)
{
memset( &Built_Buffer, 0, sizeof( Built_Buffer));
strcpy( Built_Buffer,str);
gsm_unlock();
return true;
}
else
{
gsm.gprs.Transmit_Success=0;
gsm_printf("\r\n GSM upload Failed\r\n");
gsm_unlock();
return false;
}
}
